I'm unable to insmod the modules sb_common.o and sb_ess.o (for my soundcard)

When insmod'ing sb_common.o, insmod reports (and I verified in the C source) unresolved symbol ess_dsp_reset which is in sb_ess.o

When insmod'ing sb_ess.o, insmod reports (and I verified in the C source) unresolved symbol sb_dsp_command which is in sb_common.o

How can I get these modules loaded when there's a circular dependency like this?

BTW this is on the knoppix liveCD, meaning the /lib/modules directory is readonly, and these modules are extra modules not included in the liveCD, so they are in a different (writable) filesystem than /lib/modules, and I've been unable to get modprobe to work with modules not in the /lib/modules directory
